A cheap set of LEDs is the best way to upgrade your fancy new TV

Bias lighting will enhance the picture of your screen in a dark room.

People buy a lot of TVs this time of year. In 2016, Target sold more than 3,200 TVs per minute during its Black Friday sale. And as prices shrink and screen sizes grow, the temptation to trick out your home theater area increases.

While that shiny new TV is likely an upgrade from your old set, it’s not perfect out of the box. In fact, there are lots of steps you can take to ensure the picture looks as good as possible. But one hack involves more than digging into the menus—your new TV could benefit from light shining on the wall behind the display. This is called bias lighting and luckily, it won’t cost you very much money.
